This year’s WWDC offers developers in-depth sessions and hands-on working labs to learn more about iPhone OS 4, the world’s most advanced mobile operating system.

WWDC provides a unique opportunity for developers to work side-by-side with Apple engineers and interface designers to make their iPhone and iPad apps even better.

Developers can register for the conference and buy the tickets for $1,599. Apple will also announce five iPad and five iPhone Apple Design Award winners at WWDC 2010. You can submit your nominations at developer.apple.com
